Silent Steel BoltLok Features The Silent Steel BoltLok HUB Mount and A1 Flash Hider combo is designed for fast tool-less suppressor attachment letting the shooter mount or dismount a can quickly even with gloves on. Its carbon-lock-resistant design reduces fouling buildup at the mounting interface preventing the seizing that can occur after high round counts with other quick-detach systems. A precision-machined locking interface ensures repeatable alignment every time the suppressor is reattached which keeps point of impact shift consistent across range sessions. The classic A1 flash hider shape provides familiar flash suppression performance for shooters running the 1/2x28 thread pattern in 5.56. A positive mechanical lock gives clear tactile and audible confirmation that the suppressor is fully secured removing any guesswork about whether the can is properly mounted before firing. Built for hard use in the field the BoltLok is fully compatible with Silent Steel USA s broader modular HUB-based suppressor system letting shooters move a single suppressor across multiple hosts. The finished black color matches most barrel and muzzle device finishes for a clean uniform look. This BoltLok HUB Mount and A1 Flash Hider combo is available for sale at GrabAGun for shooters who want fast reliable suppressor mounting.
